Specification of Letters Patent.

Application led' January 14, 1911. Serial No. 602,636.

To all fwhom 'it may concern:

Be it lmownthat-I, CHRISTIAN BRACK,4 a

citizen of the United States, and aresident` ing screw-threaded and alsofor cutting such, 'pipe in different lengths. The body of theY toolmaybe tem orarily clamped upon a bench, table, shel or other support,and a detachable, reversible lever is -pivoted to such body and adaptedfor use both in pipothreading and cutting, according to the position inwhich it is placed.

In the accompanying drawings, Figure 1 isa side view of my improvedtool, the same being shown applied and secured to a bench or table.Fig.' 2 is a plan view, save that a lportion of) an' adjusting screw isshown in section. Fig-3 is a perspective view of the jaws of the ratchetbench or table clamp. Fig. 4 is mainly a longitudinal section of thetool showing it secured to a bench or table. Fig. 5 is a vertical crosssectionon the line 5 5 of Fig. 4. Fig. 6 is a perspective view of thesmooth jaw for holding nickel-plated or other ornamental pipe.

' Referring, in the first instance, to Figs. 1 and 4, A indicates thebody of the tool, B,

the body in both clamping and cutting pipe, while C is a supplementalhand lever adjustably connected by a screw and nut D with the saidreversible lever.

The body Ais formed of cast metal and has suiiicient weight and size forits function. The base or underside ofthe body A is flat so that it isadapted to rest upon a bench or table. At its-larger end'it is providedwith two holes 1, adapted to receive the pivot 2 of the lever B.Adjacent to this portlon it. is provided with a notched, or ratchet,fixed jaw 3, and adjacent to this portion 'it is further provided withtwo rotary and beveled 4steel pipe-cutters 4, which are journaled in alongitudinal slot or groove of the body.

The detachable and reversible lever B has lan enlarged head 5 providedat each end to the angular jaw 3 of the body A; and again, at a pointfarther removed from the pivot, it is provided with two transversebearing rollers 8, which are so arranged as to come into direct contactwith a pipe laid 'upon the rotary cutters'4, thus serving to hold thepipe while permitting its rotation with comparatively little friction.

I The lever B is operated by a hand-lever C, which is pivoted at 9 tothe body A and adjustably connected with the free end of-` the lever B.by means-of the screw D and wing-nut 10, said free end of the lever Bbeing slotted to allow convenient insertion and removal of theA screw.

The pivot end of thel hand-lever C is arlranged in a longitudinal grooveof the body A and provided with an extension or toe 11, which, when thesaid lever C is raised :at the inclination shown in Figs. 1 and 4,#rests and bears upon the body A. When in this position, therefore, thelever C provides =a fixed point of attachment for the screw D, and, if apipe or y be inserted, as shown Figs. 1 and 4, between the opposingjaws, may be clampedl as rmly as required by 'turning the wing-nut 10;for, .without resorting to this expedient, a variable hand pressure maybe applied by pressing down :on the lever C, which will draw'thercversible lever B :down more firmly on the pipe or y. 5 It is thuswithin the power of the operator to clamp a pipe with a'moderate degree'of force, as by use ofthe nutand' screw, or a much greater force may beapplied through the medium of the lever C and the screw attachment. v a

It will be' understood that, when it is required to lay a pipe on thebody A in the angular jaw 3, the screw D and its attached nut l0 may beremoved or swung outward from the lever B, and the latter is thus leftfree to `be swung upward. The same is also true with respect to theinsertion of a pipe between the lever B and the cutters 4.

In Fig. 1, the lever Bis shown provided with an angular ratchet jaw 7corresponding to the jaw 3 of the body A, such construction being commonin pipe-wrenches for holding rough-faced pipe. If a pipe to be cut' isof sufficient diameter, the lever B may be pivoted in the lower hole ofthe body A; but, if the pipe is small, the head of the lever B will beadjusted so that the pivot pin .2 will pass ythrough the lower hole 6 inits head.

By observing Fig. 4 it will be seen that the lever B has been reversedposition, `that the numeral 12. "`he body or lower portion,

13 of such jaw is so constructed as to fitv into a socket formed in thebody A and is thus held securely in place while in use. A pipe y isshowan in Fig. 4 as arranged between the jaws 3 and 12.

The tool thus far described may be used for threading or cutting pipeheld in a vise of any suitablecharacter, vthe tool bein applied to thepipe and moved around lt-by hand in a well known manner, or as usualwith a large class of` pipe-tools. In such case, it is obvious that thetapered, grooved and extended shank of the body A would,

serve as the handle; but ordinarily, the tool will be used as anattachment of a bench, table, shelf, or other support, and for thispurpose it may be clamped at one end and secured by a screw at theother. The clamp I employ is particularly ada ted for its function, thesame consisting o two ratchet jaws 14 and lf3- see especially Fig. 3.The jaw 14 is right-,angular in form, one wing having a screw hole andthe other a slot and also ratchet teeth at 14?' on its innerl side. Theother jaw 15 is also right angular, one of its .arms having ratchetteeth 15 and also a screw opening, while the other arm is provided witha winged clamping screw 16.

As shown in Fig. 4 a screw 17 is applied to the jaw 14 and secured by anut to the body A through whichl it passes; and, as will be further seenby observation of Fig.

1, the other jaw, 15, isengaged with the jaw 14 by means of another`screw 18, and the clamp-screw 16 is screwed up against the under side ofthe projecting ledge of a bench or table. This means for detachablysecuring the tool to a support may ordinarily su'flice without the aidof a screw inserted through the opening 19 in the extreme end of theshank. It is obvious that the jaws A14 and 15 ma be adjusted verticallywith relation to ea' other in order to accommodate bench or table ledgesof dilerent thicknesses.

InvFig. 1, the clamp is shownarranged in alinement with the body A ofthe tool, ibut in Figs. 4 and 5 it is shown arranged at right anglesthereto, but the means and the manner of securing the clamp to the bodyA and to the table remain the same. The to'ol thus forms a xture of thesupport while in use, but may be readily detache when required for anypurpose.

It will be seen that by the construction and combination of partsdescribed and illus# trated in the drawings, I provide a single toolcapable of diierent functions and which is distinguished by simplicity,effectiveness,

Aand adaptation for convenient application of a great degree ofvforce.,

What I claim is In a tool of the type indicatedthecombination with thehorizontal boy having its larger end 1provided with transverse holeslocated at di erent heights for receiving a pivot pin, and having a jawportion and rollers arranged as shown, of a reversible lever having anenlarged head, each end of CHRISTIAN BRACK Witnesses:
